[dev.typeparams] cmd/compile/internal/types2: use comparable bit rather than ==() method
This removes the special "==" methods from comparable interfaces in
favor of a "comparable" flag in TypeSets indicating that the interface
is or embeds comparable. Fixes various related implementation
inaccuracies.
While at it, fix setup of the predeclared error and comparable
interface types by associating their respective type name objects
with them.
For #47411.
